To ll'wjwm 'it may Concern.'

Bel't knownthatf We, HARRY I. KLAWANS and GEORGE KLAWANS, both citizens of the United Stilles; and residents of the city of Chfago; @Gumy -of caigan-a sate of nh.v

nols, have invented a new and useful .Tuft- Making Machine, of which the follo'wmg 1s a specification.

Our invention |relates Ato machines for '10 manufacturing tuft's,-2and has' for its object the provision of a simplified form of 'such a machine which will 'have a vsmaller' number of parts, which' will Work' better, Which-,Wlll

Work quicker, which -Will make "a better tuft,

and Which'will permit `of adjustment; so as to produce' tufts of different sizes. We attain fthese fo'bjects in the mechanism' illustrated in -thef-accompanying dra-Wing, in

which machine embodying our` invention; Fig.. 2 is a front elevation of the feeding and cutting mechanism; Fig.'3 is a plan of the fixed blade'of the shears; Fig.4 is a plan ofthe movable blade of the shears Fig. 5 is a fragmentalplan 'of the mechanism shown in Fig. 2; Fig. 6 is a detail, partiallyin section, of the shaiftdriving'the feedingflmeans; Fig. 7 is a front elevation .fof la; portion of the stapler; and-Figs. 8, 9 and 1Q, are' details of portions of the stapler; p

Similar lreference y'characters referto `'similar 4parts throughout the 'several' views.

-We employ in our invention la stapling machine, such as may be purchased upon thev` market','and the details of Which constitute no portionof our present invention, except as Ahereinafter specifically Vdescribed and pointed out. Such 'a machine has a stand- 4o iardfl, astaple 'for'mngand driving am 2 is roun ed, so lthat when the formers, 8,

(Fig. 7 force the staple, 9, over the anvil the head or top of the staple Will be rounded instead of square. In order to drive the rounded staple We have rounded the end of the driver, 10, (Fig. 7); and the slots, 11,

Figure l isla side elevation ofa tufting.

(Figs."8 and 9)" are: carried past each other so that the ends of the staple will be lapped.

. Our'inventionconsists of means for feedingfthemateri'al 'to the stapler, means for cutting the material in proper lengths after it hasbeen s'tapled, and' means for actuating and-timingor synchronizing the feeding and cutting means.

The material is led to the stapler bya tube, 12, secured to the mandrel, 4, by a suitable bracket, 13. 'Upon the front end of the mandrel is'a bracket 14, in which is journaled a shaft upon one end of which, right in front of Ethe stapler, is a grooved Wheel, '15,' in the groove of which are provided teeth, 16. The bracket` 14, has an arm, 17, extending upwardly and forwardly therefrom to Which is pivoted a right angle lever, -18,up on the lower end of which is mounted a grooved and toothed Wheel, 19, smaller,Y

but similar to, and alining with the wheel, A spring, 20, and adjusting rod 21, throughthe upper end ,of the lever 18, serves to adjust the tension with which the Wheel, 19, is pressed toward the Wheel, 15.

" The Wheels 15 and 19 comprise the feeding means for`the tuft material, and to drive them thereis mounted on the other end of the shaft which carries the wheel, 15, a bevel gear, y22, which meshes with a bevel gear, 23, carried upon va shaft 24, journaled in another larm,"25, of the bracket, 13, and which is maintainedin its journal by a collar, 26,

pinned to said shaft by a pin, 27. The end in the die-for bending-the ends of the staple of the collar, 26, extends beyond the end of the shaft, 24, and is split at 28, for a purpose to be hereafter described.

To prevent the feeding Wheels from being rotated too far or from'being rotated backlWard by the stapling operation a brake band,

29,-With a friction lining,'\30, is secured at 31 lto the bracket, 14, Which encircles a hub,

-32,` upon the Wheel, 15, and a knurl headed bolt, 33, is providedlfor tightening the band and adjusting the friction.

VTo the back of the standard, l, is secured afbracke't, 34, which has right and left projections, 35 and 36. The left projection, 36, has pivoted thereto a rightangle lever arm, 37, one end of which has an anti-friction Wheel, 38, secured thereto which engages the periphery of a cam plate, 39, securedl tothe shaft, 5. To the other end of the arm, 37, is

= pivoted a link, 40, the other end of which is pivoted to another link, 41, the'l inner end of which is pivoted upon the lower portion of the projection, 36. J ournaled in the lower portion of the projection, 36, is a shaft upon the rear end of which is a ratchet wheel, 42. Said shaft is held in its journal by a split collar, 43, similar to the collar, 26. A pawl, 44, upon the link, 41, is held in engagament with the teeth of the ratchet, 42, by a spring, 45, and a coiled spring, 46, between the link 41, and bracket 36, serves to return-the link to its normal position after it has been actuated by the cam, 39. A dog, 47, upon the projection, 36, which. is also held in engage ment with the ratchet, 42, by a spring, 48, serves to prevent the rotation of the ratchet in the wrong direction. An adjusting bolt, 49, and lock-nut, 50, upon the projection, 36, which extends into contact with the lever 37, serves to 'adjust the stroke or latitude of revolution imparted to the ratchet. A ball ended shaft, 51, having pins, 52, through the balls extends into .the split collars 26 and 43.

The projection, 35, which extends to the right from the bracket, 34, has bearings, 53, one above the other so as to rotatably hold the'vertically disposed shaft, 54, from the top of which extends an arm, 55, provided upon its end with a'roller, 56, adapted to engage the cam, 39.v The roller, v56, is maintained in contact with the cam by a spring, 57, wound about the shaft, 54, and secured thereto by the screw, 58, and having its wheel, 15, is a tubular opening, 61, (shownl other end caught against the projection, 35. The lower end of the shaft, 54, is extended at right angles to form an arm, 59,' to which is secured a rod, 60, which extends forward to the front end of the mandrel, 4, to engage and operate the cutting mechanism now to be described.

Directly below the forward edge of the in Figs. 1, 2, and 5) through which thel wheels, 15 and 19, feed the material after it has been stapled. Fitting within this tubular opening is rigidly secured a tube 61a upon the lower end of which is provided' the fixed blade of the shears, 62, shown in Fig. 3. This has a shearing edge, 63, and a l stoppingA edge, 64, which positively severs such fibers as are not cut by the shearing action disposed at substantially right angles to one another,l and these edges are so disposedthat they are closely adjacent the material as it emerges from the lower end of the tube, 61a. Rotatably held to the under 'Iside of the bracket, 14, by the adjustable bolt, 65 is the movablef blade, 66, yof the shears (shown inFig. 4). In Fig. 4 the movable shear blade is shown separately but with the hole, 67, through which extends the bolt 65 to secure it in place, and the hole, 68, through which extends the rod, 60.

From the foregoing description, taken in connection with the drawings, it will be seen that by modifying the shape of the forming anvil, and driver, of an ordinary stapling machine we have produced a staple of a substantially ring shape suitable for a tuft which must have a generally round section or cylindrical shape. It will also be seen that by providing such a stapling machine with a suitable die for lapping the ends of the staple about the strands of the fabric, we have made an article of much greater strength and substantiality. It will also be seen that by adjustment of the bolt 49, the throw of the lever arm, 37, is either increased or diminished, which either increases or diminishes the revolution of the wheel'15, and thereby regulates the amount of tufting material fed to the cutter or shears, and regulates the length of tuft produced. It will be further seen that with the design of cutter employed a shearing action is secured, which is of considerable importance, as thc difficulty of severing a bunch of tufts is well known. And further it will be seen that by driving both the feeding and cutting means from a single cam mounted `upon the .shaft of the stapling machine, We

have, in a very simple manner secured the 4synchronizing vof the various parts so that feeding and. cutting will occur successively after the stapling.

i Having thus described .our invention, what we claim as new and desire to secure by Letters Patent, is

A tuft making machine comprising a staple making and driving mechanism, a shaft for driving the same, a cam upon said shaft, a lever system one end of which is actuated by said cam, a dog carried by'said lever system, a ratchet engaged by said dog, a set screw adjusting the throw of said lever system, feeding wheels for feeding material to said staple driving mechanism, said feeding wheels being driven by said ratchet, and a cutter for severing the material after it has been fed from said stapler.

in testimony whereof we affix our signatures in the presence of two witnesses.
